(54) Method and switching system for automatically controlling a call-waiting-interruption restriction and switching system


(57) A method for automatically controlling a call-waiting-interruption restriction is disclosed. In a communication system, a subscriber can be supplied with a call-waiting service permitting an interruption processing when an interruption call occurs. And the subscriber can also be supplied with a call-waiting-interruption restriction service restricting the interruption processing even when the interruption call occurs. This method includes the step (S6) of restricting automatically, when a first subscriber (B) supplied with the call-waiting-interruption restriction service has communication with a second subscriber (A) supplied with the call-waiting service, the interruption processing to the second subscriber (A).
